You can expect your coach batteries to discharge over time. Depends on what is still on. Even with the switch in the doorway turned off there is still a drain on the batteries. Propane detector, CO detector, smoke detector still remain on and drawing power. The main culprit will be the inverter. Keep it turned off until you need it to perform it's duties. Just turned on but not powering anything will still use considerable power. Won't take long for the batteries to die. When you are not on shore power, don't turn on the inverter until you need 120 volts for something.
The only way to keep the batteries from discharging is to disconnect the negative terminal while in storage. This will stop all the parasitic drains from discharging them. Of course, the detectors and everything else will not work while disconnected. Only disconnect them if stored for extended times.
